Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a hoist supports dolly, comprising a

base plate

2, 2 upside fixed mounting of bottom plate have support frame 1, the handle of U-shaped is all installed to support frame 1's both sides, support frame 1's top is equipped with curved supporting part, bottom 2's bottom four corners fixed mounting has guide rail 3, guide rail 3's spout sliding connection has slide bar 6, slide bar 6's outer end downside fixed mounting has casters 4 of area brake, slide bar 6 can stretch out or indentation, it is big more to stretch out four casters 4 area of occupation of land more, the stability of support is better, 6 retractions of slide bar can reduce to take up an area of land, the convenience is removed this dolly.

The two sliding rods 6 positioned on the same side are fixedly connected through a connecting plate 5, two symmetrical first support lugs 10 are welded on the inner side of the connecting plate 5, the first support lugs 10 are hinged to a connecting rod 9 through pins, the connecting rod 9 is a flat-bar-shaped metal rod, the other end of the connecting rod 9 is connected with a sleeve 11, second support lugs 13 are arranged on two sides of the sleeve 11, and the other end of the connecting rod 9 is hinged to the second support lugs 13 through pins.
